GREEN BAY – Aaron Rodgers’ first midweek practice since spraining his left knee in the Green Bay Packers opener wasn’t merely for show.

The Packers quarterback was limited Thursday, but coach Mike McCarthy said Rodgers did everything the team scheduled for him. That included not only throwing to receivers and tight ends in position drills, but also some team reps.

“Aaron Rodgers looked good at practice,” McCarthy said Friday. “Got everything accomplished we set out to. So today, we’ll just kind of go through the corrections.”

The plan, McCarthy said, is for Rodgers to participate in Saturday’s walkthrough before the Packers host the Buffalo Bills. Rodgers has participated in the Saturday walkthrough the past two weeks.

McCarthy shed little light on the remainder of the Packers' injuries. Among the injured players is receiver Randall Cobb, who was limited Thursday because of a hamstring injury. Cobb was listed as questionable on the injury report Friday.

“We’ll see what today brings,” McCarthy said of Cobb. “It’s unfortunate, but we’ll see how it goes.”

Cornerback Kevin King practiced Thursday for the first time since injuring his groin in Week 2 against the Minnesota Vikings. Outside linebacker Nick Perry did not practice and remains in the concussion protocol.

Both were listed as having limited participation Friday had the Packers practiced, and are questionable for Sunday.

“I think they’re both making progress,” McCarthy said, “and hopefully we'll see how Nick does today. But, I know he’s feeling good. I know Kevin’s chomping at the bit. So we’ll see how it goes.”

Right guard Justin McCray is unlikely to play Sunday after missing practice Wednesday and Thursday. McCray left Sunday’s game in Washington with a left shoulder injury.

If McCray is unable to play, the Packers will likely turn to veteran Byron Bell as his replacement at right guard.

“Byron’s played a lot of football,” McCarthy said. “So he’s looked good this week. So, we have great confidence in him.

“We’ll see where McCray is tomorrow, but I’m ready to go with Byron.”

Right tackle Bryan Bulaga is expected to play despite suffering a back injury at Washington.
